In detail
respond.io counts monthly active contacts: Growth starts at 1,000, and the price follows your audience. For a brand broadcasting WhatsApp campaigns to thousands of customers, that is coherent.
Magnitude is built for conversations to resolve. The agent reads your stock, answers, qualifies and hands over; its messages are not counted one by one, and the price is agreed on your channels and volume.
At respond.io, AI is included from Growth at $159/mo, with credits. On Starter at $79, it is not part of the included usage.
At Magnitude the agent is the heart of the product from day one.
respond.io excels at broadcasts and multi-channel marketing journeys, with TikTok and calls on top.
Magnitude is built for the inbound message: "do you still have a 42", "my order has not arrived", "can I change the date". Answer from the data, sell, hand over.
Magnitude scores every version of the agent against your real past conversations, then publishes with a history and a rollback. respond.io publishes no equivalent on its pricing page.
For a small team with nobody in charge of AI, that is what makes changing the instructions safe.
